New Scale offers a convenient MC-33DB evaluation board which includes these components, along with input and motor connectors, to take full
advantage of the NSD-1202 ASIC.
The XPD input can be used to place the ASIC in stand-by mode for minimal current consumption when the motor is not moving. Alternatively, the
designer can implement an external switch to power off the ASIC completely when the motor is not moving: the SQUIGGLE motor holds its
position with the power off.
